MENZEL exhibiting at EXPOMIN 2023 Chile

After the successful completion of the Expomin 2023, with a record-breaking participation of 1,270 exhibitors and a high attendance of over 58,000 visitors, we would like to thank our guests and business partners for visiting our stand.

The organizers emphasized that the international exhibition and congress “was undoubtedly one of the largest of all time”. For four days we presented our motor range for the mining industry as well as our capability to answer special customer requirements quickly and flexibly. We hope that the visits of our guests are the beginning of many new motor projects and exciting enquiries in the mining sector.  

he trade fair EXPOMIN is the largest mining fair in Latin America. It promotes the transfer of knowledge, experience and specifically the offer of technologies that contribute to innovation and increase the productivity of mining processes. And, it brings together all the actors in the mining sector - suppliers, professionals and executives. Despite the logistical challenges posed by the growth of Expomin - many exhibitors and visitors experienced difficulties in accessing the venue, especially regarding traffic - the Expomin 2023 edition was one of the most attended events in its 33 years of history.

The new version of the mining exhibition will be held in March 2025.

The mining industry in Chile

Mining is a key activity in the economical income of Chile. Contributing 15% of GDP and 62% of national exports in terms of value as well as 6% of the tax income. More than 800.000 people work direct and indirectly for the mining industry in Chile which makes it about 9.4% of the country’s workforce (source: EXPOMIN).

This is why exhibitors from 35 countries will attend the EXPOMIN to display their technologies, products and services. Come and meet us there as one of them!

Mining industry case study: Pit fan motors with fin cooling

One of our recent projects for the Chilean mining industry are three customised pit fan motors with fin cooling. Our engineers designed these squirrel cage motors (cooling type IC 411) in frame size 630, an extremely unusual design for motors this large.

The manufacture was complex, but the result is optimal for the constricted installation conditions in the mining industry. In order to save additional space, all connection cables are routed out of the pit fan motors and the terminal boxes are mounted outside the fans.
